DEVICE FOR CONTROL OF AN INVERTER FED ROTATING FIELD MACDEVICE FOR CONTROL OF AN INVERTER FED ROTATING FIELD MACHINE HINE |
摘要 |
1. Device for controlling a polyphase machine supplied via an inverter, the direct current fed on the input side from the contact wire to the inverter without an additional input current converter being supplied to a bandpass filter (17) to filter a disturbance frequency (fstör 1) to be suppressed, characterized in that the output signal of the bandpass filter (17) is added directly in antiphase to the desired torque value (MsoII) via a disturbing current controller (19). |
